CHAMGUN enables replacement of the drilling head inside the machine – there is no need to remove the drill for head indexing.
The CHAMGUN is the ultimate economical solution for deep drilling.
A polyamide plastic key is available for clamping and removing the CHAMGUN head.
The Drill Pocket
The drill features an innovative unique pocket which can undergo at least 15 head replacements.
The connection between the pocket and tube is done by a new welding process for high torque resistance.
A single CHAMGUN body can carry many different types of drill head profiles, designed for use on various materials.
Each drill body can carry standard drilling heads within a range of 0.2mm - 0.3mm (.008" to .012").
The CHAMGUN drill range is 9.8mm to 20.2mm (.386" to .795"). Drilling heads are available in half and whole sizes as standard items.
Each drill pocket can carry a variety of drilling head diameters and head geometries.
